Where would you add parentheses to make, nine times four minus two times five plus eight divided by two, equal 27?

Triangle xyz has vertices x(1,3), y(0,0)

What is the value of x in the following equation. -x ^3/2 = -27

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
